BENNETT HEAT EXCHANGE APPARATUS FOR COOLING LIQUIDS Filed June 2, 1954 2 Sheets-Sheet 2 ATTORNEYS 3 is discharged from the open ends 26 of the tubes into the shell 10, and passes out of the shell, through the outlet 28, to the air conditioning system or other apparatus in which cold water is required. 1

Although three cooling'coils are shown in the drawings, it should be understood that this is only for/the purpose of illustration, as one or more coils;may be located within the shell as may be required for any par.- ticular case.

It should also be understood that a plurality of units such as shown in the drawings may be connected to a common water supply and, outlet line and to a common refrigeration unit without in any manner changing the construction as illustrated and described. 1.

In the foregoing description, certain terms have been used for brevity, clearness and understanding, but no unnecessarylimitations are to be implied therefrom beyond the requirements of the prior art, because such words are used for descriptive purposes herein and are intended to be broadly construed.
